This directory contains the following lisp files:

script.lisp
primitives.lisp
primitive-lemmas.lisp
keytuples.lisp
m5.lisp
m5-lemmas.lisp
m5-fact.lisp
m5-fib.lisp
m5-magic.lisp

Copy these files to your space. I recommend creating a new subdirectory of your space, called m5/ upon which to store your M5 work. Then connect to that directory and start ACL2. Then execute

(ld "script.lisp" :ld-pre-eval-print t)
That will recertify all the books and take several minutes, perhaps as long as 5 or 10 depending on your machine.

You should then be able to start a fresh ACL2 and type:

(include-book "m5")
(in-package "M5")
to experiment with M5.

More files may be added as time goes by.
